Power Supply Assessment Model of Renewable Energy Generators – Focused on Wind Turbine Generator and Solar Cell Generator –

ABSTRAKRasio elektrifikasi di Indonesia belum mencapai 100%, penyebabnya antara lain masalah lokasi di daerah terpencil atau kepulauan dan mahalnya biaya operasi PLTD. Salah satu solusi adalah membangkitkan listrik berbasis energi terbarukan setempat. Tahap awal pemanfaatan energi terbarukan perlu dihitung faktor kapasitas (CF). Tujuan penelitian ini menganalisis CF untuk PLTB dengan metode perhitungan analitik berbasis potensi energi angin, spesifikasi teknologi PLTB dan PLTD, profil beban dan energi listrik yang dapat diproduksi untuk pengembangan sistem hibrida dengan mengambil kasus di Elat Pulau Serau Maluku. Hasil perhitungan CF untuk 5 teknologi PLTB yang berbeda dengan variasi ketinggian di Elat telah diverifikasi dengan simulasi menggunakan perangkat lunak HOMER dengan nilai rerata galat -0,030. Semakin tinggi PLTB, nilai CF semakin besar dengan konstanta 0,0030.Kata kunci: elektrifikasi, faktor kapasitas, PLTB, PLTD, sistem hibrida ABSTRACTThe electrification ratio in Indonesia has not reached 100%, the causes include problems with the location in remote areas or islands and the high operating costs of diesel power plant (DPP). One solution is to generate electricity based on local renewable energy. The initial stage of utilizing renewable energy needs to calculate the capacity factor (CF). The purpose of this research is to analyze CF for wind turbine generator (WTG) with analytical calculation methods based on wind energy potential, technology specifications of WTG and DPP, load profiles and electrical energy that can be produced for hybrid system development by taking the case in Elat Serau Island, Maluku. The results of CF calculations for 5 different WTG technologies with altitude variations in Elat have been verified by simulation using HOMER software with a mean error value of -0.030. The higher the WTG, the greater the CF value with a constant of 0.0030.Keywords: electrification, capacity factor, diesel power plant, wind turbine generator, hybrid system

Most of the electricity generation process in Malaysia using fuel sources especially coal and natural gasses. The country needs to spend higher cost to import this source since it is not a natural resource in Malaysia. In addition, the usage of coal as resources affected the environment. The extinction of this source also needs to be considered since it is not a renewable energy sources. Therefore, a prototype of mini wind turbine generator is proposed in this research in order to study the effectiveness of this type of generator since it is one of the alternatives to generate electricity. It is developed in Archimedes design by using microcontroller. The performance is evaluated by analyzing the blade material, number of blades and the environment influence on the location of wind turbine generator. The results show that the blade made from acrylic with lowest number of blades produced higher voltage and current while the location of the designed prototype at high hill area generate higher value of voltage and current compared to the beach and field area.
